n to DNA. In this way, over thousands of years, RNA, DNA, and proteins could have evolved into the complex system that characterizes life today.
Discovering that RNA can act as a catalyst, makes it easier to imagine how life began. According to Bruce M. Alberts, "One suspects that a crucial early event was the evolution of an RNA molecule that could catalyze its own replication". That makes it very obvious why it is possible that RNA was the first molecule that could replicate. These molecules then diversified into a group of catalysts that could assemble ribonucleotides in RNA synthesis or accumulate lipid-like molecules to form the first cell membranes. This clearly suggest how the first membranes could have formed.
Fox and his co-workers attempted to find an answer, to the origin of membranes and prokaryotes, in their laboratories. They heated amino acids without water and formed long protein chains. As water was added and the mixture cooled down, small microspheres were formed. These seemed to accumulate certain compounds inside them. Th
